Ajith,
Note the C++ bindings have not been removed yet from Open MPI.
You need to configure --enable-mpi-cxx in order to build them (this is
no more the default option)
As Nathan pointed out, the C++ bindings will likely be removed from Open
MPI 4, so you will have to modernize your code at some point in time.
On this mailing list, C++ users have previously pointed/recommended
- boostMPI https://github.com/boostorg/mpi
- Elemental http://libelemental.org
Though these are not part of the MPI standard, these third party
libraries provide C++ bindings.
And of course, using the C binding is a portable option that does not
require any external dependencies.
Cheers,
Gilles

Thanks for the quick reply. One of the third-party packages we're
using still depends on the C++ bindings, but I'll look to migrating
them to the C bindings.

The MPI C++ bindings were depricated more than 10 years ago and
were removed from the standard 6 years ago. They have been
disabled by default for a couple of years in Open MPI. They will
likely be removed in Open MPI 4.0. You should migrate your code to
use the C bindings.
